Age, Chemistry, and Kinematics of the Inner Galaxy Revealed by MUSE
Zixian Wang, Michael R. Hayden, Sanjib Sharma +3
The bar/bulge and inner disk are fundamental building blocks of the Milky Way, containing a large fraction of its stellar mass. However, stars in these regions are faint, crowded,…
The Nineteenth Data Release of the Sloan Digital Sky Survey
SDSS Collaboration, Gautham Adamane Pallathadka, Mojgan Aghakhanloo +209
Mapping the local and distant Universe is key to our understanding of it. For decades, the Sloan Digital Sky Survey (SDSS) has made a concerted effort to map millions of celestial…
The structure of the stellar halo of the Andromeda galaxy explored with the NB515 for Subaru/HSC. I.: New Insights on the stellar halo up to 120 kpc
Itsuki Ogami, Mikito Tanaka, Yutaka Komiyama +16
We analyse the M31 halo and its substructure within a projected radius of 120 kpc using a combination of Subaru/HSC and CFHT/MegaCam - \& -…
Towards Understanding the Milky Way's Typicality: Assessing the Chemodynamics of M31's Bulge & Bar, Thick & Thin Discs
Benjamin J. Gibson, Gail Zasowski, Anil Seth +6
We describe a novel framework to model galaxy spectra with two cospatial stellar populations, such as may represent a bulge & bar or thick & thin disc, and apply it to APOGEE spect…
